OPERATING MECHANISM FOR SHOE-POLISHING MACHINES.

Application filed. June 23, 1910. Serial No. 568,500.

To all whom it may concern:

Be it known that I, Lnwrs LEVIN, a citizen of the United States, residing at New Castle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Operating Mechanism for Shoe-Polishing Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to operating mechanism for shoe polishing machines and has for its object to'provide improved, simple, effective and reliable mechanism of this character.

IVith this object in view the invention consists in the improved construction, arrangement and combination of parts of a mechanism of the character mentioned, which will be hereinafter fully described and afterward specifically claimed. 4

In the accompanying drawings :F igure 1 is a front elevation of a shoe polishing machine constructed in accordance with my invention and showing a number of similar sections operated by the same power shaft; Fig. 2 is a plan view of one of the sections; Fig. 3 the line 3-3 of Fig. 2; Fig. 4 is a similar view on the line 4l4: of Fig. 2; Fig. 5 is a horizontal sectional view showing the means for manually operating my shoe polishing mechanism; Fig. 6 is a view similarto Fig. 3 showing the parts in a different position.

The same reference characters designate corresponding parts throughout the several views.

In the practical embodiment of my invention, I employ a frame.1, which is preferably so constructed that it may be connected or arranged adjacent to other and substan tially similar frames so that the same power shaft 2 may be utilized to operate the shoe polishing mechanism in each of said frames or sections. Theframes 1 may be of any desired shape or size and as herein shown are constructed with upright corner posts or standards 3 connected together and braced by a plurality of side bars or rungs 4 and front and rear bars 5 and 6 respectively, arranged one above the other at suitable intervals to support the shoe polishing mechanism.

is a longitudinal sectional view on Supported between the uppermost of the front and rear brace bars 5 and 6 and spaced from each other are a pair of tracks or guides 7, which as herein shown, are provided with a floor portion 8 and upright side portions 9 and 10 respectively, which are provided with longitudinal grooves 11 and 12 of any desired shape or conformation for the reception of suitable bearing flanges 13 and let upon the upright side members 15 of the shoe brush holders.

These shoe brush holders are preferably composed of the longitudinally disposed side members 15, which are arranged to be 'reciprocated longitudinally of the tracks or guides 7 and braced at their ends by cross bars 16. The shoe brush holders are suitably connected to each other by means of a transverse bar 17, to which is also connected the operating mechanism for reciprocating the brush holders to be hereinafter described. Arranged longitudinally of the tracks or guides T and between the longitudinal grooves 11 and 12 in the floor portion are troughs or recesses 19 to receive the dust and dirt brushed from the shoes before the same are polished, and suitable apertures 20 are provided at intervals to allow the dust to escape into suitable receptacles arranged below the tracks or guides 7.

The operating mechanism for reciprocating the brush holders preferably comprises a longitudinally disposed link 21 hingedly connected at its rear extremity to the transverse bar 17, between the brush holders, while at its opposite or forward end said link is bifurcated as shown and connected to the upper portion of a lever 22, by a suitable connecting bolt 23 inserted through alined apertures in the said elements. In the drawings, I have shown a plurality of apertures 24: to permit adjustment of the pivot pin. The lever 22 is preferably connected at its lower end to a rock shaft 26 which is suitably journaled at its ends in longitudinally disposed beams or braces 27, secured between front and rear brace bars 5 and 6 of the frame. Intermediate its ends, the lever 22 is provided with a plurality of adjusting apertures 28, through any of which is adapted to extend a connecting bolt or pin 29 secured to the forward end portions of the spaced parallel side arms 30 of the operating link 31, which is extended rearwardly to a position be- .yond the power shaft 2 and is adapted to inclose between its side arms an operating cam 32 secured upon said power shaft. At their rear extremities the side arms 30 of the link 31 are connected together by means of a bearing block 33, which is adapted to be engaged by the periphery of the cam 32 to reciprocate the link 31 and the lever 22 connected thereto, suitable slots 34 being arranged in the side arms 30 to allow for the reciprocation of said link beyond the power shaft 2. In order to allow the cam 32 to move the link 31 forwardly, I provide a pivoted bearing bar 35, adapted to normally lie in cont-act with the periphery of the cam 32, and adapted to be held in this position by means of the pivoted latch 36 which is weighted, as at 36, at its rearmost extremity and adapted to normally engage the edge of the bearing bar It will be apparent from this construction that when the weighted latch 36 is in its normal or lowermost position the bearing bar will engage the periphery of the cam 32 at all times, and will provide a means whereby said cam may reciprocate the link 31 in a forward direction, while its engage ment with the bearing block 33 will reciprocate said link in a rearward direction. lVhen, however, the weighted latch 36 is raised or swung out of Contact with the bearing bar 35, it will be apparent that the rotation of the cam 32 will reciprocate the link 31 to its rearmost position and will then merely swing the bearing bar 35 upon its pivot without in. any manner moving the link 31. This position, viz., with the weighted latch 36 elevated, is the normal or inoperative position of my shoe polishing machine. \Vhen the mechanism is in this position, the power shaft 2 may be rotated without operating the polishing mechanism in this section or frame, while the opera tion of similar shoe polishing mechanisms in adjacent sections or frames is not in any manner interfered with. The means herein shown and preferably employed for elevating the weighted latch 36, comprises a flexible element, such as a cord 37, which at one end is connected to the free end of said latch and at its opposite end is connected to any one of the adjusting apertures 38 in the lever 39 suitably fulcrumed to the frame work.

Means are also provided whereby the shoe brush holders may be manually reciprocated. A lever 40 is fulcrumed intermediate its ends, as at 41, upon the frame 1, and at its lower end is pivotally connected to a connecting-link 42, the opposite end of which is pivotally connected to one end of the horizontally disposed lever 43, the opposite end of which is connected by means of the link 44 to the lever 22. A suit-able connecting bolt 45 is suitably secured in the link 44, and is adapted to pass through any.

of the adjusting apertures 28 in the lever 22. The horizontally disposed lever 43 is preferably fulcrumed between its ends, as at 46, upon the post 47 extending upwardly from the longitudinal brace bar 48, arranged between the front and rear brace bars 5 and 6 of the frame work. It will be apparent that when the weighted latch 36 is lifted to allow the power shaft 2 to rotate without affecting the link 31,the lever 40 may be grasped by the hand and vibrated to rock the horizontal lever-43, in a direction to forwardly and rearwardly recipro cate the link 31, the lever 22, and the shoe brush holders connected thereto.

Pivotally connected to the inner faces of the longitudinal side members of the brush holders are provided a plurality of shoe polishing brushes 49, said brushes being preferably constructed with a backing piece 50 suitably formed, and provided so as to conform to the shape of the shoe and yieldingly follow the outline thereof as they are reciprocated. Pivotally mounted adjacent its upper extremity between the side members of each shoe brush holder and near the rear end thereof is a brush 59 which is adapted to contact with the upper portion of the toe of the shoe when the shoe brush holder is reciprocated. The pivoted brush 59 is provided upon its rear face with a spring 60 adapted to impinge against the under side of the cross-bar 16 when the brush is pressed upwardly in order to hold the brush against the shoe.

Suitable shoe supports, as 61, are provided upon the floor portions of the tracks or guides 7 in posit-ion to allow the several shoe brushes to engage the shoes during the reciprocation of the brush holders, and at each end of said shoe supports the floor portion is apertured, as indicated at 62, to allow daubing or blacking-applying brushes to be swung into contact with the shoes. Suitably supported upon the under side of the tracks or guides are longitudinally disposed cans or reservoirs 63 adapted to contain a liquid or paste blacking, and mounted at the ends of transverse shafts 6 4, suitably journaled within brackets 65 depending from the floor portions of the tracks are daubing brushes 66, which may be swung within the reservoir 63 to become saturated or covered with the blacking material and may be thereupon swung upwardly to apply the blacking material to shoes to be polished. Upon reference to Fig. 2, it will be seen that the daubers are disposed along the central line of the shoe supports and that when the daubers are at the upper limit of their vibration, they will enter between the polishing brushes and into contact therewith so that the reciprocation of said brushes will first spread the blacking evenly over the shoes and then polish the same,-as will beunderstood. I have provided means whereby the person desiring to have his shoes polished may apply any desired quantity of the blacking to his shoes by manually swing ing the daubing brushes into engagement with the shoes as often as desired. The mea-nsherein illustrated and preferably employed for this purpose comprise a grooved pulley 67 mounted upon each of the transverse shafts 64 between the tracks or guides 7 and passing around these pulleys so as to rotate them in opposite directions is a belt or cord 68, one end of which is extended through a suitable opening in the top 69 of the frame work and is provided with a suit able ring or handle 70 to be grasped by the operator. A spring 71, coiled around a shaft 64 and having its opposite ends secured respectively to the pulley 67 and the floor 8, returns the daubing brushes to the reservoir when the handle 7 0, is released. The daubers are vibrated between the tanks and the shoes by drawing upwardly on the handle 70 and then releasing said handle to permit the spring 71 to act.

When it is desired to operate the machine through the power shaft 2, the power shaft is set in motion by means of a belt or through other driving devices passing over the pulley or gear 72 upon the power shaft, the cam 32 being rotated to successively engage the bearing block 33 and bearing block 35 to reciprocate the link 31- and the shoe brush holders with their attached brushes. At any time, however, the weighted latch 36 may be elevated to release the pivoted bearing bar 35, to allow the cam 32 to rotate without reciprocating the link 31, and thereupon the brushes and brush holders may be reciprocated by manually rocking the hand lever 40.

WVhile I have described my invention as applicable to supply blacking or blacking material to the shoes, it will be apparent and is to be understood that my improved machine is equally well adapted to supply a russet or tan shoe dressing to the shoes to be polished or to be utilized to polish or clean suede or any desired colored shoes.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advan tages of this invent-ion as defined in the appended claims.

Having described my invention, I claim 1. In a shoe polishing machine, the combination of a reciprocatory member, a vibratory lever connected therewith, an operating shaft, a cam on said shaft, a link pivoted to the lever and extending'therefrom toward and past the shaft, devices mounted on said link to engage opposite sides of said cam and thereby actuate the lever, and means to release some of said devices from the cam whereby the shaft may continue to rotate without actuating the lever.
